Danny Mills has claimed West Ham would be saving £5million if they replaced Sebastien Haller with Bournemouth forward Joshua King.

Speaking exclusively to Football Insider, the former England and Manchester City defender suggested King would demand a fee of around £15million.

Football Insider revealed on Thursday the Hammers had turned the attention to the Norway international after selling Haller to Ajax for around £20million.

The Ivorian cost West Ham a club-record fee of £45million less than 18 months ago but struggled in east London.

“That figure [£20million] was only going to go down I would suggest,” Mills told Football Insider.

“Sometimes you just have to go ‘you know what let’s cut our losses, move somebody on’ and then you can bring somebody else in with that £20million.

“That £45million has been spent, it’s done and dusted. Now it’s ‘what can we recover? Let’s get £20million in, how can we use that £20million to improve on Haller. Can we do that? Yes, so, therefore, it becomes a good move.’

“I think it’s difficult sometimes for people to get their head around that because the numbers get in the way of the real situation.

“That £45million is spent, it’s gone. You’re not getting that money back. So do you just let him play out his contract in the Under-23s? Or do you get £20million in and get somebody in better.

“People get wrapped up in the numbers at times. The numbers can misconstrue all sorts in football.

“The numbers are sort of irrelevant. Is Josh King a better option right now than Sebastien Haller? Yes, he probably is.

“If it means you have to take a big loss on Haller and get King in for £15million, then you’ve sort of saved £5million is the way to look at it.
